  • Achieving ground state and enhancing optomechanical entanglement by recovering information 
    Miao, Haixing; Danilishin, Stefan L.; Mueller-Ebhardt, Helge; Chen, Yanbei (Bristol : IOP Publishing Ltd., 2010)
    For cavity-assisted optomechanical cooling experiments, in order to achieve the quantum ground state of the mechanical oscillator, the cavity bandwidth needs to be smaller than the mechanical frequency. In the literature, ...
  • Adiabatic spin cooling using high-spin Fermi gases 
    Colomé-Tatché, Maria; Klempt, Carsten; Santos, Luis; Vekua, Teimuraz (Bristol : IOP Publishing Ltd., 2011)
    Spatial entropy redistribution plays a key role in adiabatic cooling of ultra-cold lattice gases. We show that high-spin fermions with a spatially variable quadratic Zeeman coupling may allow for the creation of an inner ...

    Czubanowski, M.; Schuster, A.; Akbari, S.; Pfnür, Herbert; Tegenkamp, Christoph (Bristol : IOP Publishing Ltd., 2007)
    The structure on the atomic and mesoscopic scale of Pb adsorbed on Si(557) has been investigated by high-resolution low energy electron diffraction (SPA-LEED). Depending on Pb coverage in the range between 1.2 and 1.6 ...
  • Algorithmic landscapes : computational methods for the mediation of form, information, and performance in landscape architecture 
    Claghorn, Joseph (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2018)
    Recent design discourse in landscape architecture has shown a prejudice against rigid formal systems and has advocated systems that promote self-organization, emergence, and indeterminacy, as well as non-linear systems and ...
  • Analysis of localization phenomena in weakly interacting disordered lattice gases 
    Schulte, T.; Drenkelforth, S.; Kruse, J.; Tiemeyer, R.; Sacha, K.; Zakrzewski, J.; Lewenstein, M.; Ertmer, Wolfgang; Arlt, Jan J. (Bristol : IOP Publishing Ltd., 2006)
    Disorder plays a crucial role in many systems particularly in solid state physics. However, the disorder in a particular system cannot usually be chosen or controlled. We show that the unique control available for ultracold ...
  • Asymptotic scattering and duality in the one-dimensional three-state quantum Potts model on a lattice 
    Rapp, Akos; Schmitteckert, Peter; Takacs, Gabor; Zarand, Gergely (Bristol : IOP Publishing Ltd., 2013-01-28)
    We determine numerically the single-particle and the two-particle spectrum of the three-state quantum Potts model on a lattice by using the density matrix renormalization group method, and extract information on the ...
  • BCS pairing in a trapped dipolar Fermi gas 
    Baranov, M.A.; Dobrek, L.; Lewenstein, M. (Bristol : IOP Publishing Ltd., 2004)
    We present a detailed study of the BCS pairing transition in a trapped polarized dipolar Fermi gas. In the case of a shallow nearly spherical trap, we find a decrease in the transition temperature as a function of the trap ...
  • Block-to-point fine registration in terrestrial laser scanning 
    Wang, Jin (Basel : MDPI AG, 2013)
    Fine registration of point clouds plays an important role in data analysis in Terrestrial Laser Scanning (TLS). This work proposes a block-to-point fine registration approach to correct the errors of point clouds from TLS ...
  • Causal structure of the entanglement renormalization ansatz 
    Beny, Cedric (Bristol : IOP Publishing Ltd., 2013-02-13)
    We show that the multiscale entanglement renormalization ansatz (MERA) can be reformulated in terms of a causality constraint on discrete quantum dynamics. This causal structure is that of de Sitter space with a flat ...
  • Charge Exchange in Low-Energy H, D + C4+ Collisions with Full Account of Electron Translation 
    Belyaev, A. K.; Grosser, J.; Liévin, J.; Vaeck, N. (Basel : MDPI AG, 2002)
    We report the application of the quantum approach, which takes full account of electron translation at low collisional energies, to the charge exchange process H, D + C4+ → H+, D+ + C3+(3s; 3p; 3d). The partial and the ...
  • Cohalogenation of Allyl and Vinylsilanes using Polymer-bound Haloate(I)-Reagents 
    Domann, Silvie; Sourkouni-Argirusi, Georgia; Merayo, Nuria; Schönberger, Andreas; Kirschning, Andreas (Basel : MDPI AG, 2001)
    Polymer-supported electrophilic halogenate(I) complexes 2 and 3 promote smooth addition to vinyl and allylsilanes without loss of the silyl group. In conjunction with Amberlyst A26 (OH− -form) vinyl silanes are converted ...

    Schuster, Christian; Ali, Iftikhar; Lohmann, Peter; Frick, Annett; Förster, Michael; Kleinschmit, Birgit (Basel : MDPI AG, 2012)
    Correction on "Towards detecting swath events in terrasar-x time series to establish NATURA 2000 grassland habitat swath management as monitoring parameter". In: Remote Sensing 3 (2011), Nr. 7, S. 1308-1322. DOI: ...
  • Damped Bloch oscillations of Bose-Einstein condensates in disordered potential gradients 
    Drenkelforth, S.; Buening, G. Kleine; Will, J.; Schulte, T.; Murray, N.; Ertmer, Wolfgang; Santos, Luis; Arlt, Jan J. (Bristol : IOP Publishing Ltd., 2008)
    We investigate both experimentally and theoretically disorder-induced damping of Bloch oscillations of Bose-Einstein condensates in optical lattices. The spatially inhomogeneous force responsible for the damping is realized ...
  • Entropy generation during the interaction of thermal radiation with a surface 
    Kabelac, Stephan; Conrad, Rainer (Basel : MDPI AG, 2012)
    The entropy calculation for radiation fluxes is reviewed and applied to simple radiation-surface interactions. A plate interacting with radiation from a hot object in the zenith of the hemisphere surrounded by a colder ...
  • Euler equations on a semi-direct product of the diffeomorphisms group by itself 
    Escher, Joachim; Ivanov, Rossen; Kolev, Boris (Springfield, MO : American Institute of Mathematical Sciences, 2011)
    The geodesic equations of a class of right invariant metrics on the semi-direct product Diff(S 1)sDiff(S 1) are studied. The equations are explicitly described, they have the form of a system of coupled equations of ...

    Xuereb, Andre; Usami, Koji; Naesby, Andreas; Polzik, Eugene S.; Hammerer, Klemens (Bristol : IOP Publishing Ltd., 2012-08-29)
    Cooling of the mechanical motion of a GaAs nano-membrane using the photothermal effect mediated by excitons was recently demonstrated by some of the authors (Usami et al 2012 Nature Phys. 8 168) and provides a clear example ...

    Matjeschk, R.; Schneider, C; Enderlein, M.; Huber, T.; Schmitz, H.; Glueckert, J.; Schaetz, T. (Bristol : IOP Publishing Ltd., 2012)
    We examine the prospects of discrete quantum walks (QWs) with trapped ions. In particular, we analyze in detail the limitations of the protocol of Travaglione and Milburn (2002 Phys. Rev. A 65 032310) that has been implemented ...

    Waibel, Hermann; Pahlisch, Thi Hoa; Völker, Marc (New York, NY : Springer International Publishing, 2017)
    The perceptions of climate change and adaptation choices made by farmers are important considerations in the design of adaptation strategies by policy makers and agricultural extension services. This paper seeks to determine ...

    Torrontegui, E.; Chen, Xi; Modugno, M.; Schmidt, S.; Ruschhaupt, A.; Muga, J. G. (Bristol : IOP Publishing Ltd., 2012)
    We propose an inverse method to accelerate without final excitation the adiabatic transport of a Bose-Einstein condensate. The method is based on a partial extension of the Lewis-Riesenfeld invariants and provides transport ...
